This accessibly written book examines the most commonly taken dietary supplements, exploring what they are and what they're purported to do, and summarizing key research findings regarding their potential health benefits and risks. Today, more than 50 percent of Americans take at least one type of dietary supplement regularly.

But do these products actually work? How are they regulated? Are there any potential health risks? Dietary Supplements: Fact versus Fiction examines the most commonly used non-nutrient supplements (those that are neither vitamins nor minerals and not essential for human health). Using a standardized structure, each entry discusses a particular supplement's origins, purported benefits, potential risks, and common dosage.

Summaries of key research studies are included to help readers make informed decisions about supplements' usefulness. Introductory materials give readers a foundational understanding of how supplements are regulated and labeled and offer practical information about how to read a Supplement Facts panel.

For those interested in supplements for a particular health complaint (such as fatigue or pain), a topic finder has also been included. .
